1'0 a/ZZ whom it may concern:

Be it known that I, ALBERT B. ScHoFIELD, of Brooklymin the county of Kings and State of New York, have invented a new and useful Improvement in Fastening Devices, of which the following is a specification.

My invention relates to an improvement in fastening devices, an'd more particularly to devices for fastening and tightening the wires in connection with wire fences.

The object is to provide a combined fastener and tightener which may be furnished at a low cost and which may be employed at short intervals throughout the length of a of the Wire to effectually posts and render 1t feasible to take up the slack between the posts without requiring any changing of parts or other than unskilled labor to operate it.

A practical embodiment of my invention is represented in the accompanying drawings in which,

Figure l is a view of a portion of a wire fence in side elevation, showing one of the wires slack and the other tight, Fig. 2 is a top plan view, partly in section, on the line of Fig. l, showing the position of the parts of the fastener in connection with the slack and with the taut enlarged face view of one an end view of the same, Fig. 5 is a face view of one of the fasteners with a single staple opening, and Fig. 6 is a similar view showing the flanges at the ends of the fastener without notches.

The fastener consists of a plate A of iron, steel or other suitable material having outwardly turned flanges a at its ends. The late Ais perforated at its central portion to wire, Fig. 3 is an of the fasteners,

receive a fastening staple B. There may be two perforations a formed, one for each prong of the staple, or a single perforation a2, as shown in Figs. 5 and 6, may be formed, having sufficient length to admit both prongs of the staple. The outwardly turned anges a which preferably extend at substantially right angles to the body portion A serve as bearings for the wire, and, in the present form Fig. 4. is

shown in Figs. l to 5 inclusive, the said flanges are each provided with a V shaped notch a3 for the reception of the wire. notches a3 serve to cramp the Wire between their converging walls and thereby act as an auxiliary grip in addition to the engagement of the staple.

The wire, denoted by C, when stretched across the iianges at the ends of the body of the fastener, may be secured by placing the staple B over it and driving the staple through the perforated plate A into the post. Slight pressure upon the wire intermediateA of the flanges a will be sufficient, in connection with the V shaped notches a3, to securely hold the wire from slipping, and as the staple is driven farther into the post, the wire will be drawn over the flanged ends to supply the bend beneath the staple, and Will thus become tightened between the posts. I nd asingle staple sufficient to hold both the Wire and the plate in position, asrthe tension of the wire is exerted in a direction to hold the plate pressed against the post.

The device is adapted to use in tightening up the wires of fences which have already been built, as in building new fences, and, in connection with new fences, after the wire has been stretched nearly straight, in one long section, the above described fastening devices may be employed at intermediate points to complete the straightening of the wire.

In the form shown in Fig. 6, the notches in the iianges are omitted and the tension under the staple, as it bends the wire down between the flanges, is relied upon to hold it.

1. The fastening device comprising a bearing piece having bearings on its outer face for the reception of a wire, said bearing piece being further provided with an open space, intermediate of the bearings and back of the plane of the bearings, for the movement of the wire intermediate of the bearings toward thebearin g piece support, and a staple adapted to engage the wire intermediate of the bear- D ings and hold the Wire to its bearings and the bearing piece to its support, substantially as set forth.

2. The fastening device comprising aplate through the perforated plate, substantially having anges turned at an angle to its face, as set forth.

the flanges provided with notches havingcon- 1 A 1 verging sides for the reception of Wire, and ALBER B' SCHOIIELD W'itnesses;
